It hasn't been caesar'd that I can tell. Looking at the 6 26 11 and 11 26 20, if those are common conjuctions and we're dealing with a straight substitution, I don't think either is THE because the other would be EHx or xHT. AND doesn't seem to fit either. NOR might become YON, though. HAS could be SAY.

Interesting that the first four words start with the first four ordinal numbers, and there's a string of three words in the second line that ostensibly start with the same letter.
